PS3 3.56 hdd problem help?

Ok,

I have 2 ps3s i was trying to fix my 3.41 that was in service mode at the time and so i decided to and pulled out my hdd of my 3.56 and put it into my 3.41. well didn't do anything, but now when i put it back on 3.56 i get this reinstall / error and i put 3.56 from sonys site as if today the download and install it and i get the same screen

i originally i had the latest firmware even the v2 cause i remember going to update online and it said i had latest.

before this happened i didn't do any formating or anything. I need help getting this fixed i tried the download and to reinstall the 3.56 from there site and it just shows the same page.

i got 3.41 ps3 that works tho i was wondering if some how i can swap the hdds, or something like that to get this one working / both working even if i gotta swap hdds between them.. please help! this is insane.
